꽉 (kkwak)

What it means

Gripping or holding something really tight — a hand, a hug, a clenched fist.

When you'll see it

Grabbing someone's wrist before they walk away, a long-awaited hug where nobody lets go, a fist clenched in anger — that's 꽉. Koreans use it all the time in daily life too, and not just for gripping. It also means "packed full": a subway car so jammed you can barely breathe is 꽉 찼다, and a week with zero free time is a schedule that's 꽉 찼다.
